I have a PC 7424 and have been using it for a while. I have been using PC pads, since there is a PC store 5 minutes away making them readily available. My detailing routine usually starts with a dawn wash, claybar, 3M SMR, then NXT. I want to purchase some new products and don't know where to start. I know I need new pads, which ones should I buy? I will primarily be using them on my black 2005 Mustang GT. Next, if anyone can suggest some new products to use with the pads that would be great. I hear a lot about Zaino and have been itching to use it. Is it alright to apply Zaino using the PC?? I figured that I would post here before I bought something I might regret. Thanks in advance.
